Stupid question here: Do US residents have to pay taxes on the prizes won, or for that matter if we sell the monsters for profit? I guess I should ask my CPA but I don't really feel like having to explain everything that would entail.
I'm not an expert and this isn't tax or legal advice and I don't know what Im talking about, but AFAIK only pay taxes on ETH/BTC when you turn it to USD. I'd still ask a CPA familiar with crypto tho.
